As many of you may already be aware, Google Checkout is Google’s own checkout process. AdWords advertisers who offer Google Checkout to their customers have been eligible to use Google Checkout badges in their AdWords ads for quite some time now.

While searching this morning, conducting a bit of research on organic pet products, I came across this eye-catching Google Checkout Promotional Sale Badge, which touts a $5 off deal at Petco.com. This is a badge I’ve never seen before in the Google SERPs. Here it is:

Immediately curious about these new badges, I did some searching to look for any info on the new checkout badges. I couldn’t find a single thing on these badges, so I decided to contact the team at Google Checkout.

As part of this experiment, a percentage of search results on google.com will display the promotional badge. We’ve done experiments with our badges in the past and we’re committed to constant refinement and experimentation in the future. We have no further details to share at this time.

I’d love to see some click through and conversion data on these new sale badges! They’re certainly attention-grabbers to say the least. Is a Google Checkout promotional program in the works for all AdWords advertisers who offer Google Checkout? We’ll have to wait and see!
